Skate



IUNTTED sTATEs PATENT oEEIoE.

ISAAC W. NORCROSS AND FREDERICK M. NORCROSS, OF LOWELL, MASSACHUSETTS.

SKATE.

To @ZZ whom 'it may concern:

Be it known that we, ISAAC W. NoRoRoss and FREDERICK M. NoRoRoss, each of the city of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented an Improved Skate for Skating on the Ice; and we do hereby declare that our said invention is fully described and represented in the following specification and accompanying drawings, figures, and letters thereof.

The nature of our invention or improvement, consists in a mode of arranging, and applying springs to the runner and the foot stand of the skate, each spring constituting a part of and continuation of the runner, and being fastened either to the toe or heel of the foot stand, and disposed with regard to it as hereinafter described and as exhibited in the accompanying drawings.

The advantages, to be derived, by our invention,is greater ease to the foot, and ankle, and less liability of straining the muscles, of the skater, owing to the elestic motion of the foot stand runner and springs of the skates, which is caused by the changing motion, and weight of the person using them; another advantage being a more reven and smooth motion, while passing over rough, or what is called bubbly ice. Furthermore our mode of applying the springs to the foot rest or stand, viz, by increasing them in their width as they extend from the bearing part of the runner, gives great strength and stability not only to the skate but to the springs and runner.

In the accompanying drawings Figure l, is a profile View. Figs. 2 and 3 represent the heel of the ska-te with different springs. Fig. 4 is a perspective view.

A C, is the foot stand, or top part of the skate. B, represents the spring at the heel of the skate. D represents the spring at the toe of the skate. E, represents the runner or bottom of the skate. Fig. 5 represents the top view of the skate, the letters on all the figures or drawings represent the same parts.

In the above figures with the exception of Fig. 3, the toe spring as well as the heel spring is exhibited as a direct extension or continuation of the runner and as forming one piece of metal with it, each spring increasing in its width as it projects from the bearing part of the runner. This affords a large bearing surface for the foot rest on the springs and enables each spring to be fixed to it by several strong'screws. These screws give great lateral stability to the springs and runner. As the toe spring curves up in frontof the foot rest, it forms a spring guard, to prevent the effect or concussion on the foot above or below on the skate on rough ice. Other important advantages of the arrangements and application of the springs might be enumerated.

` We do not claim attaching the runner to the foot stand by means of springs, as we are aware that such is not new, it being the subject of the United States Patent No. 22,895 but what we do claim is- Our improved mode of arranging and applying the springs, each being a continuation of the runner, and to extend laterally and longitudinally with reference to, and to be fastened at the toe and heel of the foot stand as shown on the drawings, and asheretofore specified.

In testimony whereof we have hereto set our signatures this eighteenth day of February, A. D. 1859.

ISAAC W. NORCROSS. FREDERICK M. NORCROSS. In presence of N. G. Noaoaoss, J. N. MARSHALL.
